Abstract: An engine control system in which a rotary body rotates in association with a crankshaft of an engine and has portions to be detected every predetermined angle and at least one of the portions to be detected is missing, and a pickup is arranged near an outer periphery of the rotary body and generates a pulse each time the portion to be detected passes. In the case where a reference time point to start a measurement of a time until a control start time point to start a predetermined control of the engine is a rotational angle time point of the crankshaft when no pulse is generated from the pickup due to a missing portion to be detected, a timer is allowed to measure the time from a generation time point of the pulse generated from the pickup just before the non-pulse generation period of time during which no pulse is generated until the control start time point.

Abstract: A ring gear support member is supported radially immovably on the outer circumference of an input shaft through a ball bearing. A brake hub of a reverse brake, as supported by the ring gear support member, is made movable in the circumferential direction relative to the ring gear support member and is urged to a center position by a coil spring. When the reverse brake is applied to couple the ring gear support member unrotatably to a casing, the brake hub is supported through the coil spring by the ring gear support member. As a result, the meshing vibration, as generated at the meshing portion between pinions and a ring gear, can be prevented from being transmitted to the casing through the brake hub, thereby reducing noise.
